HPLC stands for: High-performance liquid chromatography.
High-performance liquid chromatography (HPLC) systems are used to analyze and/or purify liquid mixtures. ... The sample liquid is mixed with the mobile phase and run through a column that contains the stationary phase. The way the sample moves through the column is the basis for the analysis.
Only compounds dissolved in solvents can be analyzed with HPLC. HPLC separates compounds dissolved in a liquid sample and allows qualitative and quantitative analysis of what components and how much of each component are contained in the sample.
